Technology trend - Orgarnic EL(OLED) sealing process -

In type for white OLED(Organic Light Emitting Diode) + color filter (W + CF)' , the 'thin film sealing + resin filling (dam & fill)' process is necessary!

Device Color filter + High barrier film (Functional Films) + OLED(Organic Light Emitting Diode) panel
Final product

OLED (Organic Light Emitting Diode) display

As flexible OLED(Organic Light Emitting Diode) display,development of white OLED(Organic Light Emitting Diode) + color filter type have been actively carried out,but as the sealing process, the Process development of thin film sealing + resin filling has become an issue of emergency. At FUK, under development of resin filling (dam & fill) by thin film sealing and Glass bending lamination system by laminating of high barrier film,currently, basic study is complete and during demonstrated verification,will aim to delivery soon.

Panel structure

・White backlight + Color filter system
・White + CG type
・W + RGB etc.

Employed in the bottom emission type hollow sealing structure ,welded the frit glass to the adhesive layer is preventing the intrusion of moisture. Also, the top emission type, contact sealing structure that was filled with a highly transparent resin has been taken.   In order to realize an organic EL display of high-definition, a technique of thin film sealing L and resin filling to the CF substrate and the TFT substrate is requested.
